Foundation Shirt

Introducing the Foundation Shirt, a vintage-washed boxy t-shirt designed with raglan sleeves, raw edge detailing, and a relaxed silhouette that feels broken in from the very first wear. Crafted from substantial 320 gsm cotton, it balances structure with softness, creating an everyday essential that only gets better with time. The vintage wash gives each garment its own subtle character, while the raw hem adds a quiet, lived-in finish that feels authentic rather than distressed.

As one of the foundational pieces within the NIOSA wardrobe, the Foundation Shirt is built around the idea that lasting style begins with strong essentials. Free from excess and grounded in thoughtful construction, it is designed to become the piece you return to again and again, an everyday piece shaped by simplicity, character, and intention.
